I could not get Bluetooth working on this laptop.
As noted in Linux Wireless webpage bluetooth coexistence should be enabled by default since kernel 2.6.32.
The only references I found to this bug was this Ubuntu launchpad report.

Sound

Alsa works out of the box except for headphone detection and some issues with bumblebee.

Needs some testing on /etc/modprobe.d/intel-hda-audio.conf with the options snd-hda-intel model= parameter.
